| Abstract: Three new coordination complexes, {[Co1.5(opda)1.5(mbib)2(H2O)2]·H2O}n (1), {[Co(mpda)(mbib)]·H2O}n (2) and {[Co(ppda)(mbib)]·H2O}n (3) (H2opda=1,2-phenylenediacetic acid, H2mpda=1,3-phenylenediacetic acid, H2ppda=1,4-phenylenediacetic acid, mbib=1,3-bis(1-imidazoly)benzene), have been synthesized by using cobalt salt and bis(imidazole) ligand in the presence of different flexible phenylenediacetate blocks under hydrothermal conditions, and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray crystallography. Single-crystal X-ray diffraction analysis revealed that the diverse structures of these complexes are mainly attributed to various coordination geometries of the central cobalt(Ⅱ) cations, coordination modes and conformations of the flexible phenylenediacetic acid and bis(imidazole) ligands. Furthermore, thermal gravimetric analysis (TGA) and the electrochemistry properties of 1~3 are also investigated, and all of them have good cyclic voltammograms. |
